Is there a programmable digtial extension for the ETC? A sort of universal control deck that can be programmed (ex: assign a button to turn ETC on & off). Sort of like a programmable computer keyboard or something. Thanks.

Aside from the on/off function, any standard midi controller (with a midi din out port/or a midi to usb host converter) or computer could be used to control the ETC over midi. You could use an empty black ETC mode to simulate an ‘off’ state and store it in your ‘scenes’. The novation circuit looks like a good, if a little expensive option to me.
